STRAW-CARRIER.

SPECIFICATION forming part of Letters Patent. N0. 541,932, dated July 2,1895. Application tiled September 27,1894. Serial No, 524,266. (Nomodel.)

brating tables; and the object of the same is to provide improved meansfor additionally tossing the straw in its passage over such tables.Heretofore devices of this character have been frequently constructedwherein a fan or other device was connected with the shaking table insuch manner as to direct the air blast upwardly between the slats of thetable, and in other constructions the blast was directed longitudinallyover the table from one end or one edge. One patent of which I am awarecontained a perforated ta-l ble beneath which extendeda perforated pipedirecting a blast of air upward through the table, and included meansfor moving this perforated pipe gradually along beneath the table. Thepresent invention consists inthe employment of a single pipe locatedabout midway between the front and rear edges of the table, extending,completely across the same, and su pported permanently thereby eitherby resting on the table or by being. sunk in to it flush with its upperface. It is not contemplated to direct a blast of air upwardly throughvarious points in the table or through all parts thereof, nor to directa blast of air longitudinally of the table iu any direction; but bymeans of the devices described below, a single blast of air at about thecenter of the length of the table lifts the straw when it reaches thisline and permits it to fall again onto the table to progress toward itsrear end and there drop off. The height to which the straw is tossed is,of course, dependent on the strength of the air blast, but it is myobject not so much to thoroughly agitate the straw as to blow it out ofplace, as to simply toss it at one point near the center of the tableand allow it to fall back thereon. The

`shown therein.

mechanism by which this is accomplished forms the subject-matter of thepresent application, all as hereinafter more fully described andclaimed, and as illustrated in the accompanying drawings, wherein-Figure 1 is a central longitudinal section of one form ofthrashing-machine with my improvements applied to each of the two tablesFig. 2 is a perspective detail of the improvement detached. Fig. 3 is aperspective detail, partly in section, showing the use of a rigid pipeand joint instead of a flexible pipe.

In the said drawings, 1 designates the feed opening for the admission ofgrain to the thrasher.

2 is the cylinder or a band cutter and fee ler.

3 is the grate.

4 is the beater.

5 and 6 are two vibrating tables. mechanism for moving them.

8 is the grain b ottom.

9 is the return grain bottom.

10 is the chatter, 11 the heel riddle, 12 the wheat (or grain) riddle,13 the shoe grain bottom, 14 the blast fan, 15 the tail end spout, 16the return elevator, and 17 the grain conveyer of an ordinary or anypreferred form of thrashing'machine.,

I have shown my improvements as applied to the two tables of thismachine, although it 7is the will be'understood the same are equallyappiicable to a thrasher of any suitable form which employs the shakingor vibrating tables.

The operation of this machine is well known and needs no descriptionhere.

. Comingv now to my improvements', A is a pipe or tube standingpreferably straight.

across the table 5 and resting thereon or sunk Hush with the surfacethereof as preferred,

.and in the upper face of this pipe are perforations a as seen in Fig.2. One end of this pipe'may be closed as seen at a', and communicatingwith the other end is a piece of flexible pipe or rubber hose B leadingdown along one side of the table to an independent fan or blower C asseen. A similar hoseB" leads from the fan C to another perforated pipe Amounted on the other table 6. Suitable dampers or valves D may beemployed in these feed pipes if it is desired to cut off the blast ofair from one or both 0f the per- IOO forated pipes, or a single damperas in dotted lines at E; or, if desired, independent fans may be used,one for each feed pipe, or fast and loose pulleys on the fan-shafts forcontrolling their movements-all of which modifications will readilyoccur to the skilled mechanic and are embraced in the general idea of'myinvention. l

In operation, the thrasher having been started and straw or grain beingfed in at l, it passes under the cylinder, over the grate, under thebeater, and onto the first table 5, upon which it is agitated and tossedabout to shake out some of the grain. Continuing thence to the rear, itfalls upon and is tossed about by the second table 6 for the samepurpose, and finally falls out at the rear end of the machine. I havenoticed, however, that the tables occasionally do not break up bunchesof straw, especially when thrashing very fast and crowding the machinemore than the capacity of the same, and hence the utility of myimprovement. As a given mass of straw passes over one of the perforatedpipes A, a strong blast of air is directed into and through it frombelow, which blast scatters and tosses the wisps of straw as indicated;and which blast will increase the separating capacity in any ordinarymachine aboutonehalf. If the perforated pipe is sunk into the table ator below the level of its upper face, it will offer no impediment to thefree passage of the straw, even if the blast of air be cut off. Theiiexible feed pipe permits the perforated pipe to partake of thevibratory or shaking motion of the table; and a rigid feed pipe might beused by forming it with suitable joints where it connects withthelperforated pipe and the fan casing, as well as between such pointsas indicated at J in Fig. S-all of which forms no departure from thespirit of my invention. The exact shapes, sizes, and materials of partsare also immaterial; and

considerable further change and elaboration perforations in its upperface, one end of the pipe being closed, a flexible pipe communieatingwith the other end, a damper in said flexible pipe, and a fan forsupplying a blast of air through the flexible pipe to the perforatedpipe, as and for the purpose set forth.

2. In a straw carrier, the combination with a shaking straw table; of asingle pipe permanently carried by and sunk into the table flush withits upper face and extending across thesame at a point between its ends,said pipe having perforations in its upper face, and means tor supplyinga blast ofair to this pipe, as and for the purpose set forth.

3. In astraw carrier, the combination with a vibratory table forcarrying the straw, and a perforated pipe with closed ends restingpermanently on and extending across said table'at a point between itsends; of a fan for supplying a blast of air, and a feed pipe havingjointed connections with one end of the perforated pipe and with the fancasing and having a joint in its body between said connections, as andfor the purpose set forth.

In testimony whereof I have hereunto subscribed my signature on this the18th day of September, A. D. 189i.
